Question 1 Not yet answered Marked out of 10.00 write a ladder diagram to control the following process: if you press a pushbutton, cylinder #1 will extend and a red light will turn ON (simultaneously) for 20s. (after 20s, cylinder #1 will retract and the light is OFF) then, cylinder #2 will extend and a green light will turn ON (simultaneously) for 10s. (after 10s, cylinder #2 will retract and the light is OFF) the process will repeat itself twice. Then a yellow light will turn ON indicating the process has ended. * you should assign each input and output to a specific memory location, ex, cylinder #1 ----> Q0.0 NOTE: use a timer with a resolution of 10ms
